摘要：
This paper presents a comparative study of three types of doubly salient machines (DSMs), i.e. wound field variable flux machines (VFMs), hybrid-excited stator slot permanent magnet machines (HSSPMs), and stator slot permanent magnet machines (SSPMs). Two dimensional finite element (FE) modelling is carried out to investigate the electromagnetic performance of the VFM and the SSPM based on a global optimized three-phase 12/10 stator slot/rotor pole HSSPM. The comparison results show that the HSSPM has the highest power density which is suitable as traction machine; the VFM is favorable in low-cost, high-reliability applications due to its PM-free characteristic; the SSPM has advantage of high efficiency without the field winding. Further, the SSPM has good compatibility with high-speed drives thanks to the negligible back-EMF, and thus, the over-voltage problem can be avoided, while for VFM and HSSPM, this can also be achieved by switching off the DC coil excitation.
